Elitist Jerks [Cataclysm] Mage Simple Questions and Answers (Read the First Post)

 07/24/12, 7:31 PM #211 fourdots Von Kaiser     Blayke Human Rogue   Gilneas Just getting back to playing my fire mage after a long hiatus. I've done everything the fire compendium suggests with pretty good results, including stacking haste to 2005 and crit thereafter. I was pretty sure I understood the mechanics of haste/cast speed until I read this post on another website: "Haste Rating: This increases your casting speed (which is different from reducing the cast time of your spells)" So how is "increasing your casting speed" different from "reducing the cast time of your spells"? I always just assumed one was synonymous with the other, unless he's also referring to the lessening of the global cooldown. I apologize if this is covered elsewhere, but I did scour these and other forums looking for an answer, but to no avail. Thanks for any and all help.

Very likely he is referring to how you compute the change. People often get confused by the fact that, say, 25% increase in haste is not the same as a 25% reduction in cast time; it is actually a 20% reduction in cast time. You calculate it by taking the haste increase, h, and dividing by it: ctr = 1 / (1 + h) -- where h is haste and ctr is cast time reduction.
